Acts 15 is often misunderstood, and I do apologize if I am addressing something different than to what you refer.
[SUP]28 [/SUP]For it seemed good to the Holy Spirit, and to us, to lay upon you
no greater burden than these necessary things: [SUP]29 [/SUP]that you abstain from things offered to idols, from blood, from things strangled, and from sexual immorality.[SUP][
g][/SUP] If you keep yourselves from these, you will do well.
One needs ask himself why these things? (for instance, I don't need to be told not to drink blood! Yuck!) Why not, "Thou shalt not kill"? Was it because these were the things they practiced in their worship of pagan gods? With a small amount of research you will find it to be the case. And so, they were instructed what was most pressing at the time of their conversion. If you'll notice, Paul wasn't troubled about teaching them more, because Moses was read in the synagog every Sabbath, and eventually they would learn, just as every believer, it is a lifetime study.
[SUP]18 [/SUP]“Known to God from eternity are all His works.[SUP][
c][/SUP] [SUP]19 [/SUP]Therefore I judge that we should not trouble those from among the Gentiles who are turning to God, [SUP]20 [/SUP]but that we write to them to abstain from things polluted by idols,
from sexual immorality,[SUP][
d][/SUP]
from things strangled, and
from blood. [SUP]21[/SUP]
For Moses has had throughout many generations those who preach him in every city, being read in the synagogues every Sabbath.”
We must keep the letters in context! They were written specifically to address specific situations.
